My girlfriend keeps her promise

A true story, and probably not nearly as NSFW as most things here, but I felt like telling someone lol

My girlfriend isn’t into ballbusting or anything, but she always makes these goofy threats as jokes. Just dumb random comments. Like one time, when I went to get us ice cream, she made sure to remind me NO nuts on hers. And before I left, she yells at me “For every nut on my ice cream, I’ll kick you in the nuts!”

So, honestly just out of curiosity and to mess with her a bit, I took exactly one nut from mine, and put it right on her ice cream (she’s not allergic or anything, she easily took it out)

But when she noticed, she was really jokingly angry at me, and told me to “get ready”. I 100% thought she was kidding, but she actually kicked me, like **way** harder than I expected. I could barely stand for a bit. But it was the way she was laughing that like… awakened something? lol

She pretended to be sorry, but she was laughing through her apologies. Something about that made it so much more fun

I don’t really think it’s a fetish for her, she just thinks it’s funny. But since then, she’s been, at almost random times, threatening to punch or kick me in the balls. I always tell her not to, or that she won’t do it, so then she **has** to do it to prove me wrong. I wonder if she knows I’m doing that on purpose lol

She never does it out of anger, only when she’s in a good mood and thinks she’s being funny. But man, just yesterday she absolutely **slammed** her fist down on my balls when we were just laying in bed together, and I was rolling around in pain. She said she was sorry, and tried to “Kiss it make it better”. But after she kissed me, she just fucking punched them again even harder!

She was laughing her ass off, and honestly they’re still kinda sore, a day later. But I couldn’t be mad when I secretly thought it was really hot lol

I don’t know if this makes sense, but I think it’s less of a “ballbusting fetish”, and more like a “girl who thinks it’s cute and funny to hurt you” fetish?
